The invention provides an image shooting apparatus and an image shooting method that obtain a recovered image with high precision by using an optimal point spread function (PSF) without deriving an image shooting distance of a photographed object, an image shooting program, and a recording medium that records the image shooting program. An image shooting apparatus includes an optical system, an image shooting element configured behind the optical system; an image recovery processing portion configured to perform image processing and recovery processing on obtained image data; and a recovered image output portion configured to output a recovered image; and the image recovery processing portion includes a recovery filter storage memory configured to store multiple recovery filters pre-manufactured by using multiple point spread functions; a recovery filter processing portion configured to obtain multiple middle candidate images; and an image comment portion configured to output a middle candidate image with an optimal profile.

Image shooting apparatus that extends depth of field by recovering blurred image and an image shooting method thereof

The present invention provides a fixed focus-type photographing apparatus, which can inexpensively and simply increase a depth of field by disposing a removable light diffusion plate in an existing lens optical system, and an optical system of the photographing apparatus. A photographing apparatus includes: an optical system, including two or more than two lenses, a diaphragm disposed between any two adjacent lenses of the lenses, and a light diffusion plate disposed at a position that is in front of a forefront first lens; and a photographing element, disposed at a position that is behind a rearmost final lens, where: the light diffusion plate includes a light diffusion surface, and a distance a from a front surface of the first lens to the diaphragm is less than a distance b from the diaphragm to the photographing element.

Optical system and photographing apparatus

The shape measurement apparatus calculates a characteristic amount for a plurality of points of interest on a surface of a measurement target object, based on an image obtained by image capturing with a camera, calculates an orientation of a normal line based on a value of the characteristic amount by referencing data stored in advance in a storage device, and restores the three-dimensional shape of the surface of the measurement target object based on a result of the calculation. The storage device stores a plurality of data sets generated respectively for a plurality of reference positions arranged in a field of view of the camera, and the data set to be referenced is switched depending on a position of a point of interest.
